This invention relates to winding machines, especially of the type thatwinds flexible inaterial into large and heavy rolls. .Machines of thistype are provided with two surface Winding drums spaced apart androtatable 1n the same direction, a winding shaft, to receive flexiblematerial, being placed in the valley between the drums. In order to getthe winding shaft, with its accumulated mater1al,.

out of the machine resort has to be hadto cranes ortackle and as theobject being.

handled is of considerable bulk and weight" and the working space withinthe machine is somewhat limited diflicnlty is experienced in carryingout the operation. The main object and feature of the invention'is toprovide suitable. ejecting means to v move the winding shaft with itsaccumulated material upwardly out of the valley between the drums andoutwardly overone of said Fig. 1 showing the ejecting means ashavingmoved the winding shaft and roll out of the valley between thedrums;

Fig. 4 is a perspective detail view of the ejecting members.

Only somuclr of the winding machine as is necessaryto a disclosure ofthe invention is shown, as machines of this general type are well knownin the art. As here indicated, 1 and 2 are surface winding drums spacedapart and rotatable in the same direction. 3 is a winding shaft to beplaced in the valley be tween the drums and to receive a roll,consisting of one or'more coils, of-flexiblematerial 4. 5 is across-shaft suitably pivoted in the framework of the machine andcarrying One or more ejecting members 6 to eject the windmembersareswung against the roll to move --'ili;dicates a handwheel providedwith a sproclv of one ing shaft and roll.- Such ejecting members are ppreferably cam-shape as shown and may bear against the winding shaftitself, at either end of the r ngao there may be a single centralimember bearingagainst the roll of material; in the present case a numberof such members p are shown bearing against the'roll. During the windingoperation the ejecting members occupy the position indicated in Fig. 1,outof co ntact with the roll, said members being conveniently urgedintothis positionby their own weight, but-when the winding operation is completedyand. the roll ofmaterial is to be removed, shaft 5 isturned andthe ejecting it. upwardly and outwardly as indicated in F 3.- Owing tothe cam-shape of the ensurface of ejecting member 6, it will be seenthat: when saidsurface first engages. shaft 3,0! its roll of flexiblematerial, that portion of said cam surface which is near center of shaft5 will first be brought into action and then, as shaft 5 turns, portionsmore remote from thelcenter of shaft 5 will become effective. Theresult'is that the shaft and its roll of material, will at first bemoved relatively slowly and then with a gradually accelerated movement.This obviates the necessity of a sudden impact against the shaft orroll, which impact might strain the shaft 01' mark the roll.

Suit-able actuating means are associated with the ejecting. members.said actuating means being here constructed as follows: 7

ens-o e which. latter passes chain 9 trained at its other end oversprocket 10. Sprocket 10 carries a.- pinion 11 that meshes with gear 12on shaft 5. From this it will be seen that rotation of handwheel 7,will, through the reduction gearing specified, actuate the ejectmgmembers.

It is of advantage not merely to eject the roll but also to sustain itin a partly ejected position, such as indicated in Fig. 3 for instanceso that skids or tackle may be-b'rought into play. To accomplish this aratchet and pawl device is employed and such device may be associatedWith shaft 5 or with any rotatable member forming a part of the trainvpresent case, 'a ratchet 13 is mounted on" shaft 5 and associatedtherewith is a pawl 14 which when it engages the ratchet preventsbackward rotation. Pawl 14 is pivoted at '15 and is connected by meansof rod 16 to i foot treadle 17. A spring or theweight of the partsnormallyholds the pawl out of engagement with the ratchet, and theoperation ofthe foot treadle brings them into engagement. If desired,the foot treadle can be provided with the usual latch' (not shown) tohold the parts in engagement and .to pre vent its return. We'cla'im:

1. In a winding machine, the combination with two surface winding drumsspaced apart and rotatable in the same direction, and a windingshaft tobe placed in-the valley between the drums and to support a rollofflexible material, of ejecting means to move thewinding shaft and itsroll of flexible material upwardly out of said valley, and .out-

wardly over one of said drums including a pivotally supported memberandan actuatingdevice therefor and a ratchet and pawl associated with saidejecting means to pre-f i H vent backward and downward movement of saidejectin means. s l v 2.' In a winding machine, the combination. with twosurface winding drums spaced apart and rotatable in the same direction,and a winding shaft to be-placed' in the valle between :the drums and tosupport a ml of 'flexible material, of ejecting means to move thewinding shaft and its roll of flexible-material upwardly out of saidvalleyand out? wardly over one of said drums at first relatively slowlyand then with a gradually accelerated movement, comprising: a pivoted acam-shape engaging surface.
